On Saturday evening during NYFW, a bevy of the world’s most beautiful girls turned out to support the Knotonmyplanet campaign launch, according to DailyMail.com.

Models including Karlie Kloss, Naomi Campbell, Doutzen Kroes, Emily Ratajkowski, Joan Smalls, Martha Hunt, Sara Sampaio and Jasmine Tookes showed their support for the campaign, which aims to prevent the slaughter of elephants.

Knotonmyplanet’s passionate spokesperson, Doutzen, who recently visited Kenya, told Vanity Fair, ‘We have to raise awareness that ivory should not be a product anymore. It’s something that should be looked at that is disgusting.’

‘Elephants are being slaughtered just for that, just for their tusks, and just being left. It’s such a sad thing to see and to even think about.’

She urged friends to pledge their support by tying knots in photos and videos on their social media platforms, and spread awareness of the Elephant Crisis Fund.

Models such as Miranda Kerr, Gigi Hadid, Candice Swanepoel, Emily Ratajkowski, Cara Delevingne and Adriana Lima have already participated with Emily posting on her Instagram: ‘30,000 elephants slaughtered in a year? #knotonmyplanet. Please go online now to knotmyplanet.org to donate and share an image of YOU tying your knot.’

The original 90’s “supers,” Christy Turlington, Linda Evangelista and Naomi Campbell have also joined the campaign, posing for #knotonmyplanet and Patrick Demarchelier by posing reunited, wrapped in a big bow.

#knotonmyplanet is a campaign to support the Elephant Crisis Fund, encouraging us all to tie a knot and share to raise awareness of elephant poaching. 100% of every donation supports a coalition of vetted organizations focused on one goal: to Save Elephants Now.
